GAS RADIATOR WITH HEAT RECOVERY'AND CONTINUOUS VENTILATION.

Application filed February amount-of fuel consu1ned, mo st ofthe heat produced being wasted up the chimney when there is an exhaust pipe and, when there is none, unpleasant, noxious gases being emitted, frequently with unhealthy,-nervedisordering results.

The object of this invention is to provide a gas heating apparatus free from the above mentioned drawbacks and with which inost of the heat of the burnt gases is taken up in a special recovery chamber previous to the said gases escaping up the chimney.

The improved apparatus is composed of a readily adjustable gas burner adapted to heat to a glow a suitable radiating plate which may be constituted by blocks, flakes or threads of asbestos, or by refractory rods or plates, or by any other bodies or substances capable of becomingincandescent.

Said plate, once aglow, radiates heat, as in ordinary apparatus.

Besides said radiation, surplus heat (about 50%), instead of wasting up the chimney, is led into a chamber, which may be termed a recovery chamber, and right through which extend nests of tubes open at their ends that take up practically the whole of the fifty per cent of heat lost with ordinary apparatus. Said tubes continuously and automatically suck in cold air through their lower ends and emit very hot air through their upper ends.

Under such conditions, there is added to the heat from ordinary radiation, the still greater amount of heat continuously emitted by the tubes which, working as ventilators, produce a very energetic heating calculated to rapidly balance the temperature of the room to be heated (a result unattainable in ordinary apparatus means of radiation alone); the elliciency of the present an paratus being thus far su erior to that of the apparatus hitherto use since alliof the calories generated by the burners are utilized for "better heating.

Figure 5, 1923 Serial No. 617,184.

In order to make the invention more clearly understood there has been illustrated, as an example, an embodiment thereof in, and by the drawings appended hereto and wherein Figure 1 is a vertical section of the improved apparatus;

Figure 2 is a front elevation of the same;

3 shows conjointly a front elevation and a plan view of a glow-plate which maybe used; and

V Figure 4 is a longitudinal section of a preferred form o burner.

As shown in said drawings, the improved heater primarily comprises a main .loody consisting of two metal checks 21 and 22, connected together by a vertical plate 23 and one or more cross-braces 24.

Plate 23, which has a horizontal lower portion thatconstitutes the bottom orv base ofthe apparatus, is provided with an aperture 25 serving as an inlet for the hot gases which, after flowing over the glw-plate 33 subsequently described, pass into a vertical recovery chamber 5. The chamber is divided by vertical bafiles 7 into a number of compartments which are traversed by vertical tubes 6 whose ends open freely into the atmosphere of the room to be heated and are fitted in upper and lower tube plates 26 and 27 which are suitably positioned and secured in the chamber.

The shell or casing 28 of the aforesaid chamber is hooked to the connecting plate 9.3 at a plurality of points, as indicated at 29, 30 and 81, and the tube plates 26 and 27 are similarly affixed to said shell; the various tubes being equipped with ring joints 32 at the points where they pass through the tube plates. This arrangement, as will be understood, serves to avoid the possibility of noxious gases escaping from the chamber before reaching the outlet 8 provided at the back of the chamber and leading to the chimney (not shown). Furthermore, the use of rivets and screws is en tirely done away with, so that the construction itself is simplified and its cost reduced.

The glow-plate 33 above referredto may consist, as shown in Fig. 3, of an open frame consisting of two vertical side members or uprights 36 and horizontal top andibottoin members or rails 37 and 38; said rails being provided with notches 39 wherein the asbestus filaments 40 are engaged. The latter occupy a s'ngle plane, so that they constitute, in a sense, a highly-incandescent sheet. The plate itself is removably supported in inclined position, its lower portion being held by pins 34L- and its upper portions by lugs 35.

With the above-described apparatus, any type of adjustable-feed burner can be used. Preferably, however, the burner illustrated n Fig. 4 is utilized, the needle valve of which is adjustable at will by means of a button and permits the heating power of the glow-plate to be instantly increased or decreased accolding to the degree of heat desired. The main body of this burner is indicated at 41, and 42 indicates a piece or member of heat-insulating mater al which is interposed between the burner body 41 and the injector 43, the latter having the gas feed pipe union 46 attached to it and being provided with an air inlet 44 and with the above-mentioned needle valve 45. This type of burner permits the needle valve, once the required temperature has been attained, to be adjusted so as to ma ntain such temperature at low fuel expense.

I claim as my invention:

A heater, comprising a main body composed of a pair of vertical side members arranged in spaced, parallel relation, and a connecting plate therebetween; a recovery chamber consisting of a vertical shell disposed between said members and behind the connecting plate, with its front wall contacting with the rear face of said plate and hooked thereto at a plurality of different points, said shell being closed at its top and bottom; a burner disposed within the main body at a point forward of the recovery chamber, said plate and the front wall of said chamber having registering apertures form ng an inlet forthe gases of combustion from the burner, and said chamber also having an aperture in its rear wall forming an outlet for said gases; an incandescent heat-radiating device-supported in position to be heated by the burner; a hood attached to the main body in front of the connecting plate and its aperture and overhanging the heat-rad ating device and the burner; and a series of tubes extending vertically completely through the recovery chamber and adapted to be heated externally by the gases of combustion during their passagethrough said chamber, said tubes opening at their opposite ends to the atmosphere so as to continuously draw in cold air at their lower ends by convection anddischarge it in a heated cond tion at their upper ends.

In testimony whereof I aliix my signature.
